I think Airdroid is geared more towards accessing your phone from your PC... and its very good for that. If you want to copy files from your phone to your PC (backup photos etc), or send and receive SMS from your desktop, then Airdroid is great.

ES File explorer is designed to access the file system of your phone, from your phone, and also can be setup to 'explore' network locations. If you want to be able to access files on your network from your phone, and copy them to your phone, ES File Explorer is probably a better option.

Thanks a lot for that I've been using it for a month or so now and it's great it was cool to set up because I've never dealt with a network anything. I was amazed at how straight forward it really was. Thanks
